A marking gauge for measuring and marking desired distances on French mats. The gauge has a sheet shaped as an isosceles right triangle for alignment with a corner of a cutout area. An elongated rectangular member is secured to and overlies the sheet, having a short edge coinciding with the base of the triangle from the midpoint thereof to one 45 DEG vertex thereof and a first long side leading from the midpoint of the base through the 90 DEG vertex, bisecting it. A second long side is parallel to the first long side and extends from the 45 DEG vertex. The rectangular member provides a pocket open along each long side and closed at each end, one end being located precisely directly above the 90 DEG vertex. Inside the pocket is a removable marker scale having index markings along the first long side.
